The student's solution is completely empty, which means it fails to address the problem in any way. Without any code, we cannot evaluate correctness, time complexity, space complexity, code quality, or efficiency.

For future submissions, the student should:

1. Attempt to solve the problem first before submitting
2. Include at least a basic structure or approach if they're stuck
3. Ask for specific help if they're having trouble starting

Since the problem difficulty is marked as Medium, the student should be able to provide at least a partial solution or outline their thought process.
